Many thanx for replies/advice. The recommended approach was my gut call too.

I'm currently curing my first harvest and stealth requirements force me to cure product in unheated building. Current night time temps have been reaching approx 38 degrees F. In order to maintain reasonable temps (say 70 degrees F or so) I thought about placing 75 watt bulb in cure box...

I've come to the conclusion that prob is nute deficiency vice nute burn and turnig up the wick on the nutes.

Pics depict current status of plants; 4 weeks into grow. Yellowing occurred within 7 days of first application of Jack's Classic nutes at 1/8 strength. I've subsequently watered with 6.5 pH H2O (at same time pics were snapped). All comments/advice on whether to cut back or increase nutes...

Thanx for the quick responses. For info, I'm using Promix BX (contains little/no nutes); I'm watering every 5 - 7 days; and when using nutes (correction to above, I've made two applications), I'm using Jack's Classic at a very dilute mixture. I'm a little gun shy on nutes because on first nute...

7 weeks into veg; I've only used nutes on it once and at less than 1/8th strength so am doubtful of nute burn. Mag or calcium deficiency? Thanx for any/all assist!

Many thx to all! One week after move to larger pot, my plant has visibly improved.

My current plan is to transplant to larger pot using the same medium, Promix BX - is that something that should be avoided?

Wow - hope it wasn't anything I said that ignited this "spirited" discussion. I am very grateful for all the advice and do plan to transplant into a larger pot (and out of clear cups). In answer to questions posed: I'm using Promix BX as a medium; it's quoted as being "soil less" - mostly...

My plant does not appear healthy - request any/all advice on my prob(s). Grow is 3-4 weeks old. I have used nutes once (<1/4 strength) and plant health deteriorated rapidly after moving this plant to within 2" of lights. Thanx in advance! My setup: · “Rubbermaid” style grow...

Thanx for your response mate - good advice!

<b> All, I remain concerned about my grow and seek your continuing advice. Details of my previous post are contained below. The attached pics show current state of plant. The plant had recovered nicely from previous sins by: 1) stopping over watering; 2) use of humidity dome; and 3)...

Really appreciate additional advice/guidance. I'm happy to report there is profound improvement in my plant after just 24 hrs under humidity dome; yellowing has decreased and other leaves have developed significantly. I'm still holding off on adding weak nutes (< 1/4 strength ) until next...

More good advice- much appreciated mates!

Many thanx all! I introduced humidity dome today (zip lock bag) and will prep 1/4 strength nutes for application tomorrow. My grow medium (Promix) is definitely without nutes - bag directions state "..... add fertilizer after 7 days". I'm checking water ph with electronic ph meter (can't...

My previous post is detailed below. Changes I've made as a result of advice received: moved plant to 6 " from light changed light cycle from 24/0 to 20/4 stopped watering (until today). Today's weight of the pot was approx 50% of fully watered pot. Pics are attached - this does not appear...

I love this forum! Good tips and many thanx. Grow is on 18/6 as of today and I'm moving to water by weight at next watering

Many thanx mate - any thoughts on nutes at this early stage due to yellowing of initial round leaves?

Just started my grow and am concerned with progress; request any ideas/comments on what am I doing wrong or suggestions for improvement. My setup: · “Rubbermaid” style grow box · 6 - 100w equivalent CFLs · 50 CFM fan · 3 Nirvana...

Picked up an inoperative Hydrofarm 400W switchable ballast on Craig's List. My visual inspection reveals burnt/charred wiring on ballast transformer that I've concluded must be replaced (transformer). My question: can I purchase a ballast repair kit for a MH light and use that transformer for...
